摘要：The most tasks of the digital image processing require the implementation of the median filter in real -time, providing the constraints in terms of the size and power consumption. The parallel algorithms and structures for the realization of the median filter, which focused on VLSI technology, are discussed in this article. The authors formulated the requirements for the median filter devices of images in real time, where one of the ways to ensure them is the hardware implementation of the median filter with the extensive use of the dimensional and temporal parallelization and consideration of recent advances in VLSI technology. Moreover, the parallel algorithms of the median filter for VLSI implementations are analyzed and developed. Also, the median filter device, based on these algorithms, is developed and patented, where the introduction of new elements and relationships among them provides the performance increase in comparison with the similar devices. The structures and analytical expressions for evaluating the major characteristics of the median filter devices (equipment costs, calculation time of the median, effectiveness) are built. The structure of conveyor device is the fastest and the most effective by the criteria of the equipment use among the considered structures of median filter devices.
